Peace by persuasion has a pleasant sound, but I think we should not be able to work it. We should have to tame the human race first, and history seems to show that that cannot be done.
If there is not the war, you don't get the great general; if there is not a great occasion, you don't get a great statesman; if Lincoln had lived in a time of peace, no one would have known his name.
Peace is not merely the absence of visible conflict. Only a just peace based on the inherent rights and dignity of every individual can truly be lasting.
No weapon has ever settled a moral problem. It can impose a solution but it cannot guarantee it to be a just one. You can wipe out your opponents. But if you do it unjustly you become eligible for being wiped out yourself.
